COMBNED DESK AND @HAIER Specication ef Letters Patent. Pgjtgmmgd uga L'3922' Applicationled November 11, 1920. Serial No. 423,326.

To all whom t may concern Be it known that T, JOHN P. RICHARDS, a

citizen of the United States, residing at\ .combined desks and chairs,and more particularly to such as are adapted for school use,-one Aobjectof the invention being to provide a simple and substantial structure inwhich the chair may be adjusted vertically and in which the desk may bereadily adjusted either vertically or horizontally with relation to thechair, and in which the desk top may be raised and simultaneouslydisposed at an angle of approximately fortyfive degrees.

With these and other objects in view, the invention consists in certainnovel features of construction and combinations of parts as hereinafterset forth and pointed out in the claims. v

Tn the accompanying drawings; Figure 1 is a view of a combined desk andchair embodyin my improvements; Figure 2 is a view il ustrating thepositions of the parts when the desk top is rasedand inclined; Fi re 3is a sectional view showing the positlons of the links when the desk topis closed, and Figures 4, 5 and 6 are views illustrating variousfeatures of construction.

1 re resents one side of a book box or receptac e 2 and projects at oneend beyond the latter, and said box may be provided with a hinged cover.To one end portion of the side member l of the book box, a leg 3 issecured and to that portion of the member 1 which projects beyond thebox, two uprights 4, 5 are secured and spaced apart, the upright 4extending downwardly to form a leg 6 and the two uprights extendingequal distances above the box 2.

narm 7 on a metal bracket 8 is secured to the side member 1 and projectslaterally therefrom, said bracket having at its free end, a dependingportion constituting a leg 8a which may be provided at its lower endwith feet 9. The bracket 8 is also connected with the side member 1 bymeans of a brace Fand provided at one side with laterally projectingpins 13 to enter any of a serles of palrs of sockets 14 in the sidevmember 1 and thus the chair seat may be connected with said side memberin a manner to permit vertical adjustment of the seat. The chair seat isprovided at or near its outer side with a depending arm 15 to bedisposed alongside the leg portion 8a of a bracket 8 and said larm ismade with a plurality of holes 15, vany one of which may receive a boltto secure the seat adjustably to the leg 8a at any one of a series ofholes 8c in the latter.

The spaced uprights 4-5 provide a guideway in which a block 16l ismovable, said block being held in any desired position of verticaladjustment by means of a friction clamp 17. This clamp may be made T-shaped of spring metal, the tongue portion being secured to the block 16and the lateral portions bearing against the uprights 4 5. The pressurewith which the clamp bears against the uprights may be regulated andcontrolled by a thumb screw 18. rThe guide block 16 carries arectangular block 19 which is movable against the inner faces of the-inner faces of the uprights 4 5, and from the upper end of the block19, a board 20 projects horizontally,-the connection between said boardand block being effected and made rigid by means of braces 21.

The horizontal board 20 affords a support for a desk 22, and said deskis adjustably connected With the support, through the medium of guidestrips23 having greater length than the width of the supporting boardand secured at their ends to the bottom of the desk, thus permitting thelatter to be adjusted horizontally relatively to the chair. l

From the construction and arrangement of parts hereinbefore described,it ls apparent that the chair seat may be adjusted vertically and thatthe desk ma be adjusted either vertically or horizonta 1y or in bothdirections.

The majority of the books used by a pupil lclined position to connected.

The desk is provided with a top 24: which is so connected with the endsof the desk that it ma)7 be lraised and disposed 1n an inrFrovide agbookrest, at al 4 single operation. o permit such manipulation of the desktop, the latter is connected with the body of the desk in the manner nowto be described.

Angle pieces 25 are securedto the under side of the desk top 24andtoeach of these angle pieces two links 26-27 are pivotally zThese linksare pivoted at their lower ends to the ends of the desk and are bentintermediate of their ends, so that the lower portions will be offsetrelativel to the upper portions and the links permltted to assume thepositions shown in Figure 3 when the top is closed down upon the deskbody. It will be observed that the pivotal connections of the links ofeach pair with the desk top are closer together than the pivotalconnections of said links with the desk body. With such constructions,the desk top may be raised and caused simultaneous y to assume aninclined position at an angle of approximately forty-live degrees,suitable to provide a book rest.

Various changes might be'made in the details of construction ,of myinvention without departing from the spirit thereof or limiting itsscope and hence I do not wish to restrict myse f to the precise detailsherein set forth.

Having fully described my invention what I claim as' new and `desire .tosecure by Let ters-Patent, is

1 The combination with a side member having a plurality ofy sockets, andan upright secured to said side member, of a .bracket secured .to saidside member and having'a leg ortion,'a chair seat disposed over saidbrac et and provided with a pin to enter any of said sockets, lan armdepending from said chair seat and adjustably conl nected with the legportion of said bracket and a desk sup orted by said upright.

2.` The com ination with supportin means including arallel uprights, ofa bloc movable vertical between said`uprights,\a block secured to t evertically movable block and movable against the inner faces of saiduprlghts, a clamp secured to the first-mentioned block and engaging theouter-faces of said uprights, a horizontal desk-supportin member securedto one of said blocks, a desk mounted to slide on said member, and stris secured to said desk and passing under said member.

yIn testimony whereof, I have-signed this specification 1n the presenceof two subscribing witnesses.
